TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 784,366, dated March '7, 1905.

' Application filed September 1,1903. Serial No. 171.503.

To (all 1072 0111, it may concern.-

Be itknown that I, GEORGE E. IVEBB, a citizen of the United States, and a resident of Vestfield, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Type-WVriting Machines, of which the following is a specification.

My invention relates to type-writing machines, and more particularly to means for arresting the leading edge of the paper as it is introduced into the machine, so that the paper may always be started at the same point and properly squared and entered into the machine.

To the above and other ends, which will hereinafter appear, my invention consists in the features of construction, arrangements of parts, and combinations of devices to be hereinafter described, and particularly pointed out in the appended claims.

In the accompaning drawings, wherein like reference characters indicate corresponding parts in the various views, Figure 1 is a top view, with parts omitted and parts broken away, of one form of type-writing machines embodying my invention. Fig. 2 is a detail fragmentary perspective View, with parts broken away, of the paper feeding and arresting devices. Fig.3 is a detail fragmentary perspective view of the paper-apron. Fig. 4. is a fragmentary end elevation, with parts in section, of sufiicient of the machine to illustrate my invention, the view illustrating the disposition of the parts when the feed-rolls are thrown out of operation and the paper is introduced. Fig. 5 is a like view of the same, showingthe disposition of the parts when the paper is clamped in position by the feed-rolls.

WVhile I have illustrated my invention ap- G I plied to a front-strike type-writing machine, it should be understood that the invention may be applied to various characters of writing-machines and that numerous changes may be made to facilitate such application.

The top plate 1 of the machine is open at the front portion thereof, as indicated at 2, to enable the type-bars (not shown) to strike upwardly and rearwardly at the front portion of the platen 3.

The platen is mounted to rotate in a swingingplaten-frame 4, pivoted at 5 to a truck 6, that is supported upon suitable bearing-rollers which cooperate with tracks on a fixed plate 8, said plate being supported upon upwardly-extending supports 9, which project from the top plate. A line-spacing lever is pivoted at 11 to the carriage, and a linger or projection 12 on said lever cooperates with an upwardly-projecting link 13, that carries a line-spacing pawl 14, which cooperates with the line-spacing ratchet-wheel 15, secured to the platen. A rock-shaft 16 extends from side to side of the platen-frame and is mounted in bearings in the ends thereof, and projecting upwardly from said rock-shaft is a crank-arm 17, provided with a finger-piece 18. A paper-apron 19 extends at its upper edge from a point at the rear of the platen to the front edge of the apron where it is adjacent to the platen, and the paper-apron conforms generally at a portion thereof to the contour of the platen. This paper-apron is provided with apertured studs 20 on the rear side thereof which receive the rock-shaft 16, which passes loosely therethrough and supports the paper-apron in place. The paper-apron is apertured at different points 21v throughout the length thereof to enable the paper-feed rollers 22 to extend into the openings and to bear against the face of the platen, as indicated in Fig. 5. The paper-feed rollers are mounted ona shaft23, supported in lugs or bearings 2% on depending rigid arms or hangers 25. These arms are curved and provided with bearing edges 26 at the upper ends thereof, which are receivedin V-shaperl grooves or recesses 27 at the rear face of the cross-bar 28 of the platenframe, so that the bearing edge 26, with its bearing-groove, affords a pivotal center on which the arms are adapted to swing. Each ofthe arms 25 is apertured at 29 and is adapted to receivea screw 30, which projects freely therethrough and is received at its forward end in a threaded opening in the bar 28 of the platen-frame, to which it is secured. A coiled expansion-spring 31 surrounds each screw and bears at one end against the associated hanger 25 and at its opposite end agamst a thumb-nut 32, that is threaded on the screw, so that the springs maintain the edges 26 on the hangers seated in their hearings in the platen-frame.

From the foregoing description it will be understood that simple and etficient means are provided for readily mounting the supports for the feed-rollers in place and for removing them when desired and that by turning the platen-frame back the pressure of the springs 31 on the feed-rollers may be varied at will. In order to disconnect the feed-roller supports from the platen-frame, it is merely necessary to entirely remove the nuts 32 and the springs 31 from the screws 30, when the feed-rollers and their supports or hangers may be removed as an entirety from the machine. Projecting rearwardly from the rock-shaft 16 are fingers 33, each of which cooperates with a stud 34:, projecting from an arm or hanger 25. When a rearward pressure is exerted upon the finger-piece 18, the fingers 33 will deflect the paper-feed-roller hangers against the tension of their springs and the feed-rollers will be moved to the position represented in Fig. 4:. Adjacent to the feed-rollers and situated forward of the point where the feed-rollers contact with the platen is a series of fixed paper stops or lugs 35, which project upwardly toward the platen and are secured to the face of the paper-apron, so that they remain at a fixed or substantially fixed distance from and are never brought into contact with the platen. These paper-stops are alined longitudinally of the platen and extend throughout the length of the paper-apron, so that they are adapted to cooperate with either wide or narrow sheets of paper or small strips or cards.

When I refer herein to a fixed paper-stop, I mean a stop which is not moved in order to remove it from or to interpose it in the path of the leading edge of the paper.

From an inspection of Fig. 4 it will be observed that when the paper-feed rollers are moved to the inoperative position the paperstops 35 are adapted to arrest the leading edge 36 of the paper 37 when it is introduced into the machine and that the paper may always be started at the same position in the machine and may be properly squared by the paperstops as the paper is introduced and without the necessity of relying upon the judgment of they operator to determine whether or not the paper is properly positioned in the machine. When pressure upon the finger-piece 18 is removed, the parts will assume the positions shown at Fig. 5, with the paper-feed rollers 22 hearing against the paper. During the movement of the feed-rollers from the position shown in Fig. 4 to that shown in Fig. 5 they will bear against the paper and move the leading edge thereof out of contact with the paper-stops 35 and will press it against the platen so that the paper is free to be fed in the direction of its line-spacing movements. It will be observed that the-paper is not disturbed from the position in which it is set by the movement of the paper-feed rollers back to the operative position, and when they arrive at such position they will firmly press the paper against the platen ready to assist in feeding the paper.

A paper-table 38 is in substantial alinement with the paper-apron, so that the paper passes from the paper-table to the apron in its introduction into the machine. The paper-apron in addition to being loosely supported upon the rock-shaft 16 is held against vibration thereon by a spring-rod 39, which is secured at one end. 10, to the rear bar 28 of the platenframe and at its opposite end, 11, to the rear side of the paper-apron.

It will be seen that while the paper-feed rollers are in position to cooperate with the paper to feed it the paper cannot reach contact with the stops 35, so that they are only effective to arrest the leading edge of the paper when the rollers are moved out of contact with the platen. By reason of the fact that the paper-feeding devices or feed-rollers 22 are in advance of the paper-stops, considered with relation to the point of insertion of the leading edge of the paper or in the direction of the line-feed of the paper, the feed-rollers are adapted when restored to the normal position to force the paper away from the stops 5 and into contact with the platen without disturbing the arrangement of the paper attained with the aid of the stops.

The stops extending, as they do, at various points throughout the length of the paperapron, which is substantially equal to the length of the platen, are adapted to cooperate with narrow or wide sheets of paperor cards of varying'widths, and for this reason it is preferred to have the stops at various points throughout'the length of the platen, though obviously this need not be the case. Instead of a number of separate stops a single stop of sufiicient length may be employed, and various other changes may be made without departing from the spirit of my invention.

Certain of the features shown in the accompanying drawings form no part of my present invention, but are claimed in a separate application filed herewith.
